The highly diastereoselective addition of allylzinc bromide to imines derived from (R)-phenylglycine amide is reported. Homoallylamines with high enantiomeric purity are obtained from the adducts in three steps on removal of the chiral auxiliary by means of a nonreductive protocol. Removal of the auxiliary by hydrogenation leads to the saturated amines, also in high enantiomeric purity. [reaction: see
据报道,将烯丙基溴锌高度非对映选择性地加到衍生自(R)-苯基甘氨酸酰胺的亚胺上。具有高对映体纯度的高烯丙胺是在通过非还原方案去除手性助剂的三个步骤中从加合物获得的。通过氢化除去助剂得到饱和胺,也具有高对映体纯度。[反应:看文字]
